CNET Car Tech reviews the 2009 Mercedes-Benz S550.

Ah, the good life, where your car negotiates traffic speeds for you and gives you a massage. The Mercedes-Benz S550 actually does all of the above, using its adaptive cruise control to not hit the car ahead and letting you choose from four settings on its massage seats. This car also gives you an enhanced view out the front for those pitch dark nights driving through the mountains, and a blind spot-warning system, alerting you to cars in the lanes to either side.

There is quite a bit to like about this car, but in our hypercritical way, we found a few features that didn't meet our ideal. For one, the car's iPod integration doesn't actually let you select the music you want to hear. And although it receives traffic information, displaying it on the navigation system's maps, it will blithely let you drive right into bad traffic jams.
